To all `whom 'it may camerati 4 Be 'it known that we, WILLIAM E.-'MCKAY,' of Milton, in thecounty of yNorfolk and State .of Massachusetts,'and HERBERT N.-

CHENEY, of Boston, inthe county of Suolk 'and AState of Massachusetts,have invented' certain \new i and useful Improvements rrr4Watf'er-(u`r-as Generators, of-which the tollen generating water gas bythe combination of.'

ing is a specification. This invention hasor its objectv to 'provideafwatergas generator adapted to continuously carry on the recurrent`process of the lcomponent elements of steam withincandescent coal orsimilar fuel.

The invention is embodied Vin a'water gas generator, which, while"ofjordinary con-` struction, so far as the mea-ns for combining the saidelements with the fuel are concerned, has certain novel featuresrelating to the practical continuity of the process,

said novel features including notonly a grate having movable bars whichare operable from the exterior ofthe generator without interruptingtheordinary recuirent'proc- .-ess, so that the base portion of the 4bedof fuel may be cleaned by suitably moving the grate'bars, but 'alsogas-tight sight openings located below-the grate and arranged in suchrelation to ythe gratebar operatingme'ans as to permit the gas .maker toascertainthe condition of the jbase portion of the fuel bed while the*same is being.' cleaned, the lgas maker being ltherefore'.guided sothat he is enabled to determine when the re has been cleaned to theproper extent, andrto' avoid such an excessive cleaning' ofthe iire` aswould 'involve Waste of fuel and'injurious or' l destructive heating'wofthe grate bars.

In carryingout ourinvention, we provide thegenerator with a grate composed -of'a plurality of movable bars 17,which are adapted tobe operated to shake down ashes .and clinkers fromthe base portion ,of the bed of fuel supported by the grate, means beingprovided whereby anattendant is enabled to move the grate bars to cleanthe base portion of the bed, said operatin 'I neanshav.- ing provisionsfor preventmg't e escape 4of air or gas from the generator- In theembodiment of our inventionhere shown, each grate bar 17 is providedwith.' an individual 'oplerating niembenhere shown -as a shank 18engaged with a socket 19 in one end of the, grate bar, and a squaredouter end adapted :to be engaged Vby .a crank or'handle, the' saidoperating member passin through a stuffing box 20 affixed to the wall ofthe generator,
